NOTES FOR USE OF STSHST.ICN SATELLITE ICON FILE ----------------------------------------------- 1. File STSHST.ICN is a satellite icon file for use with STSORBIT PLUS, Version 9517 or higher. It depicts the space shuttle docked on the Hubble Space Telescope. 2. In order to use STSHST.ICN, the file must be copied to a new file which has a name of the form "#nnnnn.ICN", where "nnnnn" is the five digit NORAD Number of the space shuttle mission. If the NORAD Number of the space shuttle mission is 24804, then use the following DOS command to create the new icon file: COPY STSHST.ICN #24804.ICN The following sample space shuttle 2-line elements illustrate how to determine the NORAD Number. It is the five digit number in positions 3 through 7 of the two data lines, "24804" in the sample. Note that the NORAD Number is DIFFERENT for each space shuttle mission! STS-84 1 24804U 97023A 97137.96043866 .00002664 00000-0 32928-4 0 108 2 24804 51.6558 237.7137 0010222 26.1284 148.9878 15.59394064 427 3. If HST 2-line elements are being used instead of space shuttle 2-line elements, use the following DOS command: COPY STSHST.ICN #20580.ICN The following sample HST 2-line elements illustrate the data. HST 1 20580U 90037B 99036.01008271 +.00001065 +00000-0 +98822-4 0 01368 2 20580 028.4698 180.7896 0014302 289.0724 070.8312 14.87418625282116 4. STSORBIT PLUS will automatically select the ICN file if present. Once the space shuttle undocks from HST, delete the #nnnnn.ICN file created in Step 2 or Step 3 and the satellite icon will return to normal.
